FOUNT-HOLDER FOR CENTRAL-DRAFT LAMPS.

SPECIFICATION forming part of Letters Patent No. 430,871, dated June 24, 1890.

Application filed March 5, 1890. $rial No. 3%,705. (N0 model.)

To all whom it may concern:

Be it known that I, JOHN C. MILLER, of M eriden, in the county of New Haven and State of Conn ecticut, have invented a new Improvement in Fount Holders for Central Draft Lamps; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specificatiomand represent, in

Figure 1, a side view of the fount-holder and fount in partial section; Fig. 2, a top view of the holder, the fount removed, showing the perforated disk on the bottom; Fig. 3, a vertical section of the perforated disk removed.

Thisinvention relates to an improvement in fount-holders for central-draft lamps in which the fount-holder is of cup shape, supported upon a standard and adapted for the fount to be removably set into the said holder, rosting upon the upper edge of the holder as a support, there being an opening through the bottom of the fount-holder for the flow of air into the central-draft tube. These holders are usually made from sheet metal.

The object of the invention is to strengthen the holder and to provide an airdistributer in the holder, through which air will flow to the central-draft tube in the foun t, and which distributer will so equalize the current of air as to prevent disturbance from outside influences tending to make the How of air to the lamp irregular; and the invention consists in the construction as hereinafter described, and particularly recited in the claim.

A represents the fount-holder, which is of cup shape, and is made from sheet metal. Its outline may be of any of the usual shapes, according to the demands of the trade or the taste of the manufacturer.

I5 represents the fount, which is set into the fount-holder, and is constructed with a flange C to rest upon the top of the fountholder in the usual manner.

The fount-holder rests 011 the top of the standard in the usual manner, the upper portion of the standard being open for the admission of air thereto, which may flow through the bottom of the holderinto the oentral-draft tube. The fount-holder is constructed. with an opening I) through its bottom for the passage of air into the central draft passage E of the fount.

Around the opening D in the bottom of the fount-holder is an upturned flange (1. Over this opening the air-distributer F is set. This distributer is constructed, as seen in Fig. 3, of a disk of metal having a flange 1) around its edge, which flange 1), when the disk is set upon the flange a, will extend down around the outside of said flange a, and thus locate the disk F at the bottom of the fount-holder.

The central portion of this disk is perforated with numerous holes, as seen in Figs. 1 and 2, so that the opening into the fount-holder from below is composed of numerous small apertures, which serve to equally distribute the air as it passes to the interior, and pre vent irregular flow of the air which would otherwise arise from outside influences, such as a sudden agitation of the air around the lamp, as by blasts of wind or bodies moving in the vicinity. The disk is pierced at one or more points, as at d, through which bolts or screws are applied, extending downward into the standard, and which serve not only to hold the disk in place, but also, through the So disk, to hold the fount-holder in its proper position on the top of the standard.

Instead of perforating the disk, the central portion may be composed'of fine woven wire,- which produces substantially the same result, such woven wire being a well-known substitute for perforated sheet metal in lampwork. I therefore by the term perforations wish to be understood as including such equivalents.

I am aware that the fount-holders of eentral-draft lamps have been constructed with perforated air-distributers over the opening through the bottom of the fount-holder leading to the central-draft tube. 1 therefore do not broadly claim such an air-distributor; but

That I do claim is-- A fount-holder for central-draft lamps having an opening through its bottom with an upwardly-turned flange around said opening, into the standard as a means for securing combined with a disk adapted to set over said disk and fount to the standard, substansaid opening and constructed with a flange daily as described.
